If you are taking off in a crosswind, you will require a rudder defelction in the opposite direction to the wind direction (left crosswind requires right rudder) to maintain the runway centreline. There is therefore no need for an actual deflection of the rudder to yaw the aircraft into wind. On realeasing the rudder from the position you had it in to maintain the centreline, the aircraft will naturally yaw into wind itself.
I personally release the rudder to neutral as the aircraft gets airborne. This almost always results in the aircraft assuming the appropriate heading to maintain the runway track all by itself. However, once the rudder is centered you should use aileron only (assuming your aircraft has a yaw damper) to correct the aircraft track if need be, exactly as you would for any other turn.
